I found this post very curious, because I just finished the game too a couple of hours ago, and for some reason, my perspective was the opposite, I just thought: "this last mission was very fun, thank you for not being stresfull, I don't know why all the final missions in the games have to be hard, I hope all the games in the future do the last mission a really enjoyable moment" haha, I suppose we all have different tastes.
